Error including once class into another

[Arc]

Hey guys. I have 2 simple classes "NavClass" and "SuccessErrorClass". In the "SuccessErrorClass" I include the navclass and create a new NavClass object. But I am getting this error where I create the new NavClass object.

"Parse error: parse error, expecting T_OLD_FUNCTION' orT_FUNCTION' or T_VAR' or'}'' in ...successerrorclass.php on line 9"

I use the navclass in the exact saem way in other places in the site and it works just fine so I am confused.

Any help is appreciated, thanks!

here are the two classes code

SuccessErrorClass

<?php
include("navclass.php");


class SuccessErrorClass{
$nav = new NavClass();//error occurs here

function ErrorMessage($msg){
	?>
	<td valign=top>
	<br>
	<p><b>Error: <?php echo $msg; ?></b><br>
	If this error persists please write us an email by <a href="mailto:[e-mail]">clicking here</a>
	</td>
	<?php
	$nav->Footer();
	exit();
}//end ErrorMessage

function SuccessMessage($msg,$forward, $forwardWhere) {
	?>
	<td valign="top">
	<br>
	<p><b>Success:</b> <?php echo $msg; ?>
	<br>
	<br>
	Your are now being forwarded <a href="<?php echo $forward; ?>"><u><font color="#406766"><b><?php echo $forwardWhere; ?></b></font></u></a> If you are not transferred please click <a href="<?php echo $forward; ?>"><u><font color="#406766"><b>here</b></font></u></a>
	<META HTTP-EQUIV="refresh" CONTENT="3; URL=<?php echo $forward; ?>">
	</td>
	<?php
	$nav->Footer();
}//end SuccessMessage

}//end class SuccessError

?>

NavClass

<?php

class NavClass{

function TopNav(){
	require_once("topnav.php");
}//end TopNav

function SideNav() {
	require_once("sidenav.php");
}//end SideNav

function Footer() {
	require_once("footer.php");
}//end SideNav

}//end class NavClass

?>

I figured out that apparently you cant declare the new object Globably to the class for all functions to use. If I create a new object in each function it works ok....

Any idea why?

Have a good read about classes and objects in PHP before trying to use them 🙂

You can't declare objects of another class within a class, if you want to incororate the functions in your "NavClass" class into your "SuccessErrorClass" class then you can just use inheritance using "EXTEND" and call the functions as if they were declared in your current class

ie
class SuccessErrorClass extends NavClass {
$nav = new NavClass();//error occurs here

function ErrorMessage($msg){ 
    ?> 
    <td valign=top> 
      <br> 
      <p><b>Error: <?php echo $msg; ?></b><br> 
       If this error persists please write us an email by <a href="mailto:[e-mail]">clicking here</a> 
    </td> 
    <?php 
    Footer();  // rather than $nav->Footer()

What do you mean by this? Of course you can declare an object within another class.

class SuccessErrorClass
{
  var $nav;
  function successErrorClass()
  {
    $this->nav = new NavClass();
  }
   function ErrorMessage()
  {
    // ...
    $this->nav->footer();
    // ...
  }
}
$success = new SuccessErrorClass();
$success->ErrorMessage(); // The return value of Navclass::Footer()

Use aggregation not inheritance if you just need one object to access the methods of another. And read the manual page, really.
